Hello, Mrs Hg137 here.
A while back – in fact it was at the UK Mega in August 2013 – we acquired two trackables. These are small tags, identified by a code, which can be placed in geocaches and then moved around from place to place by other geocachers; often trackables have a specific mission, such as travelling round the world, and some of them travel thousands and thousands of miles. We’ve decided to release our trackables near to each other, but some way away from home, to see if they can make their way back. This sounds like a race doesn’t it? Did I mention that we’re both quite competitive?
